SAMPLE DISTRIBUTION SYSTEM LAYOUT USING SYNERGEE SIMULATION SOFTWARE


 SAMPLE DISTRIBUTION SYSTEM LAYOUT USING SYNERGEE SIMULATION SOFTWARE
Distribution system layout example using a simulation software


Effective distribution line analysis requires complete considerations of all involved line equipment that exist in utility’s distribution system. Also, computing for utility’s distribution system’s loss is of the same importance since all electrical equipment connected to the system has its own loss contribution that depends on the reliability of the available information.

The analysis of distribution system’s loss starts from the substation feeder all the way down to the customer’s service point. Due to the complexity of the distribution system, manual computation and analysis tends to be found impractical and time consuming for the part of the person analysing.

Through the aid of modern computer simulation software, distribution loss computation became more easily available for monitoring and analysis. Furthermore, field assets like lines, switches, capacitors, transformers, etc., has been accounted effectively through the help of computer aided database.

At present times, various power system simulation soft wares are offered and are available for utility’s use. Soft wares like, synergee, etap, dms, etc., are some of the known tool for this specific purpose. These soft wares possess its own advantage and disadvantage compared to other soft wares i.e the capability to compute and analyse various electrical processes.

The image below shows a sample distribution system using Synergee Electric software. Like any other distribution system, the network starts first at the substation feeder and supplying the area through the primary lines. Also found in the sample network are electrical devices usually used in distribution system like, disconnect switches, capacitors, secondary lines; fuse cut-outs and other devices needed for distribution system operation.

Having all the necessary electrical devices in the distribution system network, loss analysis has also been readily available for computation since synergee includes load flow analysis. Also, because of this network, loss segregation procedures can also be easily done since synergee offers per equipment loss analysis.

Listed below are some of the important parameters necessary for effective distribution system loss analysis in using the Synergee Electric Software;

1.    System voltage
2.    Wire size for primary lines
3.    Wire length per section for primary lines
4.    Wire size for secondary lines
5.    Wire length per section for secondary lines
6.    Distribution transformer ratings (kVA, %IZ, etc.)
7.    Customer loads (kVA & kVAr)
8.    Other electrical devices (AVRs, Capacitors, switches)

PARTS OF A POWER TRANSFORMER

What are the name of the basic parts of a Power Transformer? We can not deny the fact that only a handful of electrical engineering students are presently familiar with power transformers especially on what it looks like. Unlike a transformer we found in our homes, a power transformer’s appearance and construction is somewhat more complicated. It is not just a simple winding with a primary and secondary terminal although basically any transformer has one. The function that a power transformer plays in an electrical system is very important that an electric utility can not afford to loss it during its operation. Our discussion here will focus more on the basic parts and functions of a power transformer that are usually tangible whenever you go to a substation . Although not all power transformers are identical, nonetheless they all have the following listed parts in which the way of construction may differ.

ELECTRIC MOTOR FRAME SIZE STANDARD SPECIFICATIONS

ELECTRIC MOTOR FRAME SIZE STANDARD SPECIFICATIONS How is electric motor frame size being specified? Motor frame dimensions have been standardized with a uniform frame size numbering system. This system was developed by NEMA and specific frame sizes have been assigned to standard motor ratings based on enclosure, horsepower and speed. The current standardized frames for integral horsepower induction motors ranges from 143T to 445T. These standards cover most motors in the range of one through two hundred horsepower. Typical example of where you can locate the frame is shown in Fig 1.2.D – Frame No. The numbers used to designate frame sizes have specific meanings based on the physical size of the motor. Some digits are related to the motor shaft height and the remaining digit or digits relate to the length of the motor. The rerate, or frame size reduction programs were brought about by advancements in motor technology relating mainly to higher temperature ratings of insulating mate...

ELECTRIC MOTOR NAMEPLATE SPECIFICATIONS

How do we interpret an electric motor nameplate? Motor standards are established on a country by country basis.Fortunately though, the standards can be grouped into two major categories: NEMA and IEC (and its derivatives). In North America, the National Electric Manufacturers Association (NEMA) sets motor standards, including what should go on the nameplate (NEMA Standard MG 1-10.40 "Nameplate Marking for Medium Single-Phase and Polyphase Induction Motors").
